Anak's notes Thanks for such a long note. I tied to go thorugh stuffs you aske me to do, however to answer these questions concretely is not easy. Firstly, I would say that it is nice to see all the course contents of both parts: atomic physics and physical optics. This make us easier follow the curriculum with self works. I am looking at those earlier notes in the phys261 webpage. I have made a very short note,this time only to be polite, please find in the attachment In my understanding atomic units are numerical values used to express the physical quantities in atomis scales like mass and charge of electron. Though, these can also be expressed in SI units. The advantages of doing so is to calculate and represent the atomic quantities differently? Mass(kg), length(m) and time(s) are fundamental units and rest can be derived in SI unit system In atomic unit system, fundamental mass is the mass of electron, fundamental length is Bohr's radius and fundamental charge is the charge of electron. In calculations mass and charged are equal to unity and the Bohr's radius is the distace between ground state hydrogen electron and nucleus. This is a approximation since electron position is probabilistic i QM. Quantities in atomic physics can be derived together with another fundamental constant ''Planck's constant'' |
